THE VENUE

Belvoir Castle looks majestic at noon. It looks like a nightmare at 3:00 AM. The postcard views of the Midlands completely lie to you. Once the sun goes down at World’s Toughest Mudder 2027, the beautiful estate grounds turn into 24 hours of pure, unadulterated mental liquidation.

World’s Toughest Mudder 2027 is coming back to Belvoir Castle, and the energy is already reaching a boiling point. This is the most prestigious, community-defining 24-hour extreme endurance event of the year, transforming the historic estate into an electric, high-stakes battleground. You will be pushing through up-scaled obstacles, freezing midnight drops, and brutal terrains that demand total mental resilience. Teams are already forming, strategies are being mapped, and registration spaces are disappearing rapidly. If you hesitate now, you are choosing to sit out the ultimate event of the year. Claim your registration spot today and step up or enjoy watching the highlight reels on Monday morning knowing you chose the easy way out.

TOUGHER TOGETHER
24 hours is a long time, but you don’t have to go about this challenge alone. Take advantage of our team relay options – allowing you to tackle the WTM course in teams of up to 4 people.

Recruitment starts now, and no one is off limits. Fire up the group chat and rope in everyone from your closest friends and family to your best friend at work, or even that one Mudder you made friends with three years ago on Mud Mile.
BUILD YOUR TEAM
Adaptive Athletes
Tough Mudder has always had a clear vision of creating an environment for athletes to work together to overcome fears and challenges. Our Adaptive Athlete Programme connects athletes and course guides to conquer each obstacle course in a way that best suits them.

BREAKFAST OF CHAMPIONS
Back for 2027 and served with a side of smug satisfaction, our post-event brunch is open to both participants and pit crew. It’s your chance to refuel, swap war stories, and witness the glory of the awards ceremony, because nothing says “champion” like a trophy in one hand and a bacon sandwich in the other.

Spaces are limited, and once they’re gone, that’s it. Don’t be the one stuck outside, nose pressed to the glass, mourning lost bacon.

We have something for every racer (and their mighty pit crew recruits).
